# Table 2 Shape characteristics of the estimated species segregation function \( \hat{\varPsi}^{\prime }(r) \) and the size segregation function \( \hat{Y}^{\prime }(r) \). Intercept – from linear regression, expression of maximum size segregation; Slope – from linear regression, expression of how rapidly \( \hat{\varPsi}^{\prime }(r) \) and \( \hat{Y}^{\prime }(r) \) tend towards a value of 0; Range – difference between average distance to first and 30th nearest neighbour, SSDL – sum of squares of deviation from linearity (Eq. 8)

Plot | Intercept | Slope | Range (m) | SSDL | |||
